FAQS on cng type 3 cylinder

Q: What is the key difference between Type 3 and Type 4 composite CNG cylinders?

A: Type 3 cylinders use an aluminum liner wrapped with composite fiber, while Type 4 cylinders feature a full-composite polymer liner. Type 4 is lighter but typically more expensive, whereas Type 3 offers better fatigue resistance.

Q: What are the advantages of Type 3 CNG cylinders over other types?

A: Type 3 cylinders provide a balance of lightweight design, high durability, and corrosion resistance. Their metal-composite hybrid structure ensures safer high-pressure storage compared to all-metal designs.

Q: In which applications are Type 3 CNG cylinders commonly used?

A: Type 3 cylinders are widely used in commercial vehicles, buses, and trucks due to their optimal weight-to-strength ratio. They’re also preferred for retrofit CNG conversions in automotive systems.

Q: How do safety standards differ for Type 3 and Type 4 CNG cylinders?

A: Both follow ISO 11439 and NGV2 standards, but Type 3 cylinders undergo additional tests for metal-composite bonding integrity. Type 4 requires stricter polymer-liner permeability evaluations.

Q: What maintenance is required for Type 3 CNG cylinders?

A: Regular visual inspections for fiber damage and hydrostatic testing every 3-5 years are mandatory. Avoid impacts and extreme temperatures to preserve composite structural integrity.
